Database management is a system of coordinating the information that a company needs to run its business operations. It involves storing and distributing data it to users and applications, editing it as needed, monitoring data changes, and protecting against data corruption due to unexpected failure. It is an element of an organization’s overall informational infrastructure which aids in decision making and growth of the company as well as compliance with laws like the GDPR and the California Consumer Privacy Act.

In the 1960s, Charles Bachman and IBM among others developed the first database systems. They developed into information management systems (IMS), which allowed huge amounts of data to be stored and retrieved for a range of purposes. From calculating yanfashion.com.vn inventory, to aiding complicated financial accounting functions, and human resource functions.

A database is a set of tables that organizes data in accordance with a specific pattern, such as one-to many relationships. It utilizes primary key to identify records and permits cross-references among tables. Each table is comprised of a set of attributes, or fields, that provide information about data entities. Relational models, created by E. F. “TedCodd Codd in the 1970s at IBM, are the most well-known database type currently. This design is based on normalizing the data, making it more easy to use. It is also easier to update data since it doesn’t require the modification of several databases.

Most DBMSs are able to support different types of databases, offering internal and external levels of organization. The internal level is focused on cost, scalability, as well as other operational issues, including the physical layout of the database. The external level is the representation of the database on user interfaces and applications. It can include a mixture of external views based on different data models. It could include virtual tables that are computed using generic data to improve the performance.
